Title: Inspecting device for package of parts
Inventor: YOSHIDA MOTOHIKO
IPC: H04N7/18
Filed: 1986-05-27
Abstract: PURPOSE:To shorten the inspection time of parts by radiating the parts with orthogonal light beams slantingly from above, photographing them by TV cameras, and comparing and computing the length of the right-angled crossing point of the slit light beams onto the parts by using their image outputs. CONSTITUTION:The X-Y tables 3 and 3 of the 1st and the 2nd image input devices 20 and 30 are brought under the position control of X-Y table controllers 5 and 5 at the same time to move chip parts 1 and 1 to be inspected next to specific positions. When the chip parts 1 and 1 are positioned at the specific positions, the TV cameras 6 and 6 photograph the chip parts 1 and 1 and the image outputs of the image input devices 20 and 30 are stored in a CPU 4. Then the CPU 4 compares and computes the length from the right-angled crossing point of the slit light beams projected on the parts and judges whether or not the parts are arranged at the correct positions. Further, the CPU 4 processes the image outputs of the devices 20 and 30 while the tables 3 and 3 are moved by the controllers 5 and 5. Consequently, the inspection time of parts is shortened.

Title: Vortex flowmeter
Inventor: INADA YUTAKA
IPC: G01F1/32
Filed: 1988-05-20
Abstract: PURPOSE:To stress a phase change between two ultrasonic waves as caused by a Karman's vortex while cancelling effects due to an external factor such as temperature change, by comparing phases of two ultrasonic wave signals with a phase comparator. CONSTITUTION:When the rear half of a Karman's vortex passes through a propagation path of two ultrasonic waves, a phase of the ultrasonic wave (a) is delayed while the phase of the ultrasonic wave (b) is advanced. Hence, as one Karman's vortex passes through the propagation path for ultrasonic waves, a phase difference between the ultrasonic waves (a) and (b) changes sinusoidally by a half a cycle. The generation of the Karman's vortex can be detected by checking a change in the phase difference of the ultrasonic waves (a) and (b). Moreover, a flow velocity and a flow rate of a fluid can be measured by counting the number of Karman's vortex per unit time. That is, when the phase difference of the two ultrasonic wave signals (a) and (b) reaches theta, the phase comparator 11 outputs a voltage Vtheta corresponding to the phase difference thetaat an output terminal 12.

Title: Variable attenuator
Inventor: GEERII ESU BAATA
IPC: H03H11/24
Filed: 1988-05-20
Abstract: PURPOSE:To improve an operation in a microwave frequency range by equipping a feedback circuit to feedback the output of a reference cell to the gate of the electric field effect transistor (FET) of an attenuating cell and the reference cell. CONSTITUTION:A reference attenuating cell 12 executes the feedback control of a main attenuating cell 10 through an operational amplifier 14 and this reference cell 12 is designed so as to be electrically equivalent with the attenuating cell 10 in a characteristic impedance. A control signal that an amplifier 60 outputs to an output conductor 38 is changed by an attenuation control signal impressed to the reference output signal of an NORD 44 and a control terminal 16. This control signal is fedback to the gate of a parallel FET 54 and controls a reference circuit operation and the impedance of the NORD 44 is made equal to that of a NORD 46. Since the same control signal is impressed to an FET 34, the attenuating cell 10 and the reference cell 12 are samely operated. Thus, regardless of the change of the attenuating quantity of an attenuator, since the characteristic impedance can be always maintained to be constant, the characteristic is stabilized over a wide range.

Title: Power supply, discharge lamp lighting apparatus and lighting apparatus
Inventor: MITA KAZUTOSHI
IPC: H02M7/5387
Filed: 1996-05-17
Abstract: PROBLEM TO BE SOLVED: To surely start a switching device of an inverter even when an impedance of a control terminal circuit of a switching device is low. SOLUTION: Since a charging voltage of a capacitor C8 is low when the power switch is turned on, transistors Q3, Q4 are turned off and a resistor R12 is disconnected from the gate circuit of a transistor Q1 and an impedance of this circuit becomes high. Therefore, after a charging voltage of a capacitor C1 rises and a transistor Q2 turns on and off, even if the potential generated in the secondary side CT2 of a saturable transformer is weak, this voltage is high enough to exceed the gate voltage of the transistor Q1 and thereby the switching of the transistors Q1, Q2 are surely started. Thereafter, when a charging voltage of a capacitor C8 rises and a zener diode ZD turns on to turn on Q3, Q4, the resistor R12 is connected to the gate circuit of Q1 to make an impedance of this circuit low and raises high frequency powers outputted from the transistors Q1, Q2 up to the rated value.

Then, the log manager inquires the processing conditions of cancel to the status monitor and judges whether the cancel processing is finished or not. When the cancel processing is finished, the log manager registers the contents of the facsimile transmission instruction from the user into the log file.
